S YRINGE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 429,374, dated June 3, 1890.

Application filed February 5 1890.

To all whom it may concern.-

Be it known that I, ALFRED E. CHARLES- WORTH, of Seattle, in the county of King and State of Vt ashington, have ,invented a new and Improved Syringe Attachment, of which the following is a full, clear, and exact description.

My invention relates to improvements in syringe attachments; and the object of my invention is to provide a simple and convenient device by means of which an injection may be easily taken without undressing, and by means of which the strain usually accompanying such an operation may be in a great measure avoided.

To this end my invention-consists in the peculiar construction of the various parts and their novel combination.

This construction will be hereinafter fully described, and specifically pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a vertical longitudinal section of the device; and Fig. 2 is a plan view of the same with the cover, pump-handle, and injecting-tube removed.

The case A is provided with a horizontal partition B, near the upper part thereof, with a vertical partition 0, which extends across the case above the partition B, thus dividing the upper portion into two parts, with a tank D, which occupies the back part of the case below the partition B, with a downwardlyswinging door E, which fills the end of the case below the partition B, andwith a removable cover, which is indicated by the dotted lines in Fig. 1. The tank D is made preferably of lead, and fills the back portion of the case below the partition B, thus leaving a chamber or space F in the front portion. The door E is provided at its lower edge with suitable hinges a and at its upper edge with a suitablecatoh b to hold it in closed position.

Directly above the chamber F, and attached to the partition 0 and the front of the case, is a seat H, which is like an ordinary watercloset seat, and to the lower side of whichis attached a funnel H, which may be made of any suitable material, and which terminates Serial No. 339,319. (No model.)

in a spout whichextends downwardly through the partition B and into the chamber F.

In the rear of the partition 0 is a funnel J through which passes the plunger L, which extends nearly the entire length of thepump, and is provided at the top with an operatinghandle L and at the bottom with an ordinary lifting-valve d and suitable packing d, to make the necessary suction. The pump is provided at its lower extremity with an ordinary check-valve e and at the top with a suitable packing f, which fits closely around the plunger L, between the pump-shaft K and the cap K, thus making a tight joint, so that when the plunger is drawn up the liquid in the tank will be drawn through the valve e, and when the plunger is depressed the liquid will be forced through the pipe M.

I 'do not confine myself to the use of the above-described pump, as any suitable pump having a removable top maybe used. It is desirable, however, that the plunger and valves should be of. brass.

A pipe M, which is preferably of lead,-is connected with the pump K and extends along the partition B. It is provided with an elbow at the end, to which is coupled a rubber tube N. The tube N is provided at its free end 'with an ordinary syringe-nozzle N, which is used in the usual way.

It will be seen by reference to the drawings that the front part of the case is widened to make room for the seat H and chamber F; but the case may be made in any desired form solong as there is room for these parts.

The device is operated as follows: A person 7 I l 7 I I tube N, and nozzle N into the body of the patient. If an injection is to be given with oil, the pump-cap K is removed and the pump K filled with oil.

In practice this device will be found much preferable to the ordinary syringe, as the patient can sit upon the seat and take an injec tion Without straining. The liquid may also be injected with a great deal more force, and the degree of force may be very nicely regulated by the vigor with which the pump-handle is Worked. When an evacuation is made, the excrement will pass through the funnel H to the vessel in the chamber F.

Having thus described my invention, I claim as new and desire to secure by Letters Patent all arranged and adapted to operate substantially as shown and described.
